METHOD OF MAKING BOOTS AND SHOES.

Application filed March 22, 1926. Serial No. 96,551.

The term shoe occurring. in the specification and in the claims is to be interpreted to include the term boot.

The present novel method invention relates to improvements in the making of shoes, and more particularly to the cushioning of shoe bottoms in; a better manner than heretofore by adapting the cushioning material to removal from the shoe and renewal of the same during wear without otherwise affecting the construction of the shoe.

The cushion bottom'shoe, or cushion sole shoe, as commonly termed, is a great desideratum and variousprocedures directed it thereto have been proposed from time to time, but, so far as I am aware, none has given the desirable degree of satisfaction. The reasons being that under the forms of procedures involving permanent embodiment of resilient material in a shoe forepart, as distinguished from the forms of procedures involving embodiments adapted to removal of the resilient material from the shoe forepart and renewal of the same during wear, the cushioning effect is of short duration comparatively to the life of the shoe. On the other hand, under the forms of procedures involving insertion in a shoe forepart, over the inner surface of the insole, of resilient material of athickness sufficient to properly cushion the shoe bottomand which involve adaptation to its removal from the shoe and its renewal during wear, the construction of the shoe is thereby seriously impaired in that the given size of the shoe is then disadvantageously decreased. Moreover, at the heel portion, resilient material which is adapted to removal and renewal during wear without otherwise affecting the 40 construction of the shoe, disadvanta eously alters the original tread of the shoe 1n that the heel of the wearer is thereby elevated too high relatively to the forepart.

This novel method invention has for one objective the elimination of the objections noted, by the provision of a recess on the inner surface of the forepart of the insole.

of a shoe, formed by forcing the wearing surface of the insole below its marginal portion to a depth suflicient to properly receive resilient material of a thickness suflicient to properly cushion the shoe bottom without dis-advantageously decreasing the given size of the shoe, and byadaptation of such resilient material to removal from the shoe and renewal during wear without otherwise affectlng the construction of the shoe;

A further objective of this novel method invention is to likewise provide a recess on the inner surface of the heel part of the insole of a shoe, and to provide resilient material adapted to fill the recess and adapted to removal and renewal during wear without otherwise affecting the construction of the shoe and without disadvantageously decreasing the given size of the shoe or altering the original tread of the shoe.

As shown in the drawings:

Fig. 1, is a plan view of an ordinary outsole having its heel part recessed.

Fig. 2 is a longitudinal sectional view of a Goodyear welt shoe in which the outsole shown in Fig. 1 is secured to the welt and the heel of the insole in the usual manner.

Fig. 3, shows a similar view of the welt shoe placed on the ordinary iron shoe form, of a direct pressure leveling machine, having, however, two novel projections on its plane surface.

Fig. 4, is a plan view of theinsole of the shoe shown in F i 3.

Fig. 5, shows aTongitudinal sectional view of the welt shoe removed from the form after having been leveled and recessed.

Fig. 6, is a side elevation of a slip-sole 85 having resilient material cemented to its forepart and heel part. 7 Fig. 7, shows the welt shoe, as shown in Fig. 5, but with the slip-sole, and resilient material applied within the recesses. 1

Figs. 8 and 9, are details of a modified form in the .ractice of this novel method invention an arc to be described later.

Referring to the drawings, 1, represents an ordinary outsole, which, in accordance with the novel method invention, is recessed at 2; and which recess in actual practice, starts at about three eighths of an inch from the extreme edge of the outsole, and said recess is of its greatest depth at 3, and tapers gradually therefrom to the point 4. The said outsole is united to the welt shoe 5, best shown in Fig. 2, and, astherein shown, the shoe forepart has no filler between the outsolev and insole, which forms the recess 10; and the recess 2, in the outsole, forms a recess between the outsole and insole at the heel part of the shoe. The shoe at this stage, as in the usual practice, is passed to the levelin machine; and in the practice of this nove 110 projection 8, at the heel part thereof, is of;

the shape and thickness corresponding substantially to the shape and depth of the recess 2, in the heel part of the outsole; and

the projection 9, at the forepart thereof, is substantially of the shape and depth of the recess 10, between the outsole and insole of the shoe forepart. As shown in Fig. 3, when the leveling pressure is applied to the shoe,

the insole, which is advisedly thin and when of leather which may have been dampened preparatory to the leveling operation andpreferably tempered, is forced into the re-- cesses-at the forepart and heel part by'the form 6, under the leveling pressure by the form 7. The form 6, is best shown in Fig. 3. When removed from the leveling machine, the shoe is in the condition shown in Fig. 5; the in'sole 11, having been forced into the recesses 2 and 10, caused the recesses 2' and 10', to be formed on the inner surface of the insole of the shoe. The shoe is now adapted to receive the slip-sole 12, which is, preferably, covered with cementitious material on its inner side, and which is of the size and shape of the insole in the shoe,- and of about one sixteenth of an inch thick, and which has the resilient material 13, which is preferably of cork, cemented to the forepart thereof; and the shape and thickness of the said resilient material is substantially of the shape and depth of the recess 10', on the forepart of the .insole, which recess is of a depth suflicient to properly reperformed as usual.

ceive resilient material of a thickness sufficient to properly cushion the shoe bottom; and at the heel part of the slip-sole is cemented the resilient material 14, which is preferably of sponge rubber, and which has substantially the shape of the recess 2', and which protrudes over the recess as it is advisedly extra thick at the heel-end, as at 15, best shown in -Fig. 7, to allow for the pressure of the foot and resultant compression of the rubber. After the heeling operation and then preferably after the heel breasting operatlon, the slip-sole and resilient material cemented thereto is applied to the shoe, and the cemented marginal portion is united to the insole, and then a last, preferably of one half size smaller than the given size of the shoe, as in the usual practice of replacing shoes on lasts, is inserted in. the shoe and the remainder of the shoemaking operations are Referring to the modifications shown in Figs. 8 and 9 a McKay ty e of shoe 16, is shown in pulled over con ition on a last,

and, in view of forming a recess on the inner surface -of the forepart of the insole 17 substantially like the one formed on the insole of the welt shoe herein shown, I pro vide a narrow strip of leather 18, on the marginal portion of the insole, extending from the corners of the tip, and box-toe piece to the ball line, and therefrom the said strip is skived down, as at 19. After the practice of this novel method on McKay shoes or on any other type of shoe adapted.

to the practice of the method, the remainder of the shoemaking operations are performed as in the usual manner.

It is generally recognized in the art that a welt shoe is best adapted to a cushion bot tom, and that cork material is best adapted to the cushioning of the forepart of any shoe, and I, therefore, have chosen to show herein a welt shoe and corkfor cushioning the forepart, and rubber for cushioning the heel part, but it is to be appreciated that this novel method invention is not thereby lim ited to practice on any special type of shoe, nor to a claim or adoption of any particular kind of cushioning material, and the term resilient occurring in the specification and in the claims is to be interpreted in its broadest sense.

Furthermore, the present method invention eliminates in a welt .shoe, having an inseam, such as herein shown, the possibility of the fore art caving in under the effect of wear an causing thereby the-inseam to beadaptable to the practice of this novel meth od, may ,be used at the option of the shoe manufacturer.

It is to be noted that the invention covers two distinct features, in that it provides a cushion at the forepart, and a cushion at the heel part of a shoe, and the specification and the appended claiming clauses are to be interpreted so as to cover each of said features independently ofthe other whenever the context so permits.

Having explained the nature of my method invention and described a form of practice which is the best now known to me, what I claim as new and desire to secure by Letters Patent of the United States is 1. That method of making shoes comprising the formation of a recess in the outsole of a shoe and the formation of a recess in the insole ofthe shoe by forcing the surface s of the insole into the recess in the outsole, and the insertion of resilient material in the recess formed in the insole;

2. That method of making shoes comprising the formation in the inner bottom of 5,

shoe having an insole and an outsole, and a recess 'therehetween m the rorepart of the shoe, of a recess in the insole h forcing the insole into'the recess between t e insole and i outsole of. the shoe, and the insertion of a material in the formed recess in the insole.

In testimony whereof I have signed my name to this specification.
